Greater than 600Mbs Data Rate .. 3V Power Supply Operation .. 5ns Maximum Differential Pulse Skew .. 1.5ns Maximum Propagation Delay .. Low Power Dissipation .. Power-Off Protection .. Meets or Exceeds the TIA/EIA-644 LVDS Standard .. Flow-through Pinout Simplifies PCB Layout Description This dual driver is designed for high-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. The driver translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350mV, which provides low EMI at ultra-low power dissipation, even at high frequencies. This device is ideal for high-speed transfer of clock or data. The FIN1027 or FIN1027A can be paired with its companion receiver, the FIN1028, or with any other LVDS receiver.
